Does anyone know what the "b/g protection" mode do in the stock firmware?

Just did a quick google search and sure enough safe TX power does vary depending on the router (hardware), as suspected:

Source DD-WRT:Quote:
How high should I set the transmit power on my router?
Somewhere around 84 mW is considered to be the best setting for maximum power with minimum noise for most hardware. The Buffalo WHR-HP-G54 has a built-in amplifier. The amplifier is turned on by default; the radio power should not be set above 10mW (on v23SP2), or 70mW (on v24). The forums have had discussions about what power level is safe, with little consensus. Use common sense and don't set the power higher than you really need to. If you're trying to get more range, consider using a different antenna and make sure you have a clear line of sight, two of the most critical factors in your router's range.

From a network security standpoint, the transmitter power level should be just enough to cover the intended area reliably. Optimal power settings can be determined by trial-and-error.

END QUOTE

I don't know how long ago it was written (technology changes of course) but it at least gives a glimpse into power settings amnd how they vary.

Linksys uses 100mW (I read a while back) as the default on the E4200.

I plan to ask Asus what the recommended and safe TX (tranmit) power value is for the RT-N66U given that they are reportedly updating the GUI values as per G37x.
It might be worth others reaching out too (since different tech support reps may give different answers based in their knowledge oad lack thereof).

It ensures that the radio listens long enough to be sure it doesn't miss packets from these slower protocols

Hey guys, I don't know whether it's a bug or a bad configuration I made?

I activated QoS, entered my maximum down/upstream (currently 64MBit/5MBit) and left it in the "automatic mode".

The problem I encounter is that transferring a file via wireless lan to my local NAS, the transfer-speed slows down to 64MBit. After disabling QoS I get over 170MBit. I don't get the point why QoS wants to manage traffic inside my home network? My old FritzBox didn't behave that way.

edit: Sorry guys, actually I made a mistake. I entered the up- and downstream data in the wrong fields (upstream-rate in the downstream field, downstream-rate in the upstream field). But entering the data in the right fields makes my situation even worse

Default RT-N66U fw coming...

Guys just fyi: I'm told the fw update should be available early next week. This is the one that's supposed to fix NAT L and DLNA.

Cheers,
G37x

After doing many research online. It's a good thing I finally came across someone who has the same problem. I thought it was my rt-n66u because nobody seems to bring up this issue.

All of my wireless file transfers go very slow when enabling QOS. A 100 meg file usually takes 30 seconds on my previous router. On the rt-n66u with QOS enabled it take about 15 minutes.

This definitely has to be a bug .

I've been pretty disappointed so far with this router. I understand that it is a brand new release and was excited about it. The specifications and all sounds great but after paying almost $200.00 for this router I was hoping that it would work for the reasons I purchased it for.

Yeah.. Network speed slows down to the value you entered in the upstream field. I really think this is a bug, so I'm going to report it tomorrow.

@Creep89 and Lucinda: Ya, I noticed the same thing as well. Setting the QoS limits LAN/WLAN bw instead of just WAN. I also found it weird and it does sound like a bug. Didn't experiment further. I will also report it as a bug (have a slew of other GUI related tidbits that I have been meaning to send) so hopefully it will get addressed.

Bring it all to Networking_Support@asus.com.
Make sure you have the newest firmware flashed.

Yep I'm running the latest firmware available, it's the *.90.
